A continuing focus of my work was obtaining perpendicular magnetic anisotropy that leads to greater device scalability, better state lifetimes and lower power consumption. Half metals such as full-Heusler Co2MnSi and other variants that have been shown to have fully spin-polarized conduction electrons. Half-metals are predicted to improve device state discrimination. My thesis project sought to combine perpendicular anisotropy and half-metallicity into a single material that would be ideal for certain high performance spintronic applications. Additionally, I worked with materials exhibiting non-trivial topological electronic behavior. For example, full-Heusler Co2TiGe has been predicted to possess Weyl fermion states that are the source of extremely large Berry curvatures. These materials exhibit large, and potentially quantized, anomalous Hall conductivity, which could be used in certain magnetic sensor applications. In the past, I have contributed to the study of ultrathin epitaxial Fe films grown using molecular beam epitaxy (MBE) on MgO(001) surfaces. The films are studied in-situ using reflection high energy electron diffraction (RHEED), magneto-optic Kerr effect (MOKE), x-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). The films are then capped and characterized ex-situ by superconducting quantum interference device magnetometry (SQUID). Show less
